Hariho ubwoko bwinshi bwo gukata udukariso twihanganira isoko. Ubwiza bwa gants zaciwe zirwanya ni bwiza, ninde utoroshye kwambara, nuburyo bwo guhitamo kwirinda guhitamo nabi?
Uturindantoki tumwe na tumwe twirinda ku isoko dufite ijambo "CE" ryanditse inyuma. Ese "CE" bisobanura ubwoko runaka bw'icyemezo cyo guhuza?
Ikimenyetso "CE" nicyemezo cyumutekano, gifatwa nka pasiporo kubakora kugirango bafungure kandi binjire kumasoko yuburayi. CE bisobanura ubumwe bwi Burayi (Guhuza iburayi). Ubusanzwe CE isobanura uburayi, none usibye gukurikiza ibipimo ngenderwaho, ni ayahe mahame agomba gukurikiza uturindantoki twirinda gukata?
Uturindantoki turinda kurinda ibyangiritse cyane cyane byubahiriza EN 388 isanzwe, verisiyo iheruka ni verisiyo ya 2016, hamwe na ANSI / ISEA 105 yo muri Amerika, verisiyo iheruka nayo ni 2016.
Mubisobanuro bibiri, imiterere yimvugo yo kugabanya urwego rwo guhangana iratandukanye.
Gukata uturindantoki twihanganirwa byemejwe na en standard bizaba bifite ingabo nini nini yanditseho ijambo "EN 388". Hano hari imibare 4 cyangwa 6 yamakuru ninyuguti zicyongereza munsi yikigereranyo kinini. Niba ari imibare 6 ninyuguti zicyongereza, byerekana ko ibisobanuro bishya bya EN 388: 2016 byakoreshejwe, kandi niba ari imibare 4, byerekana ko ibisobanuro byakera 2003 byakoreshejwe.
Ibisobanuro by'imibare 4 ibanza ni bimwe, ni "abrasion resistance", "guca intege", "kwihangana", no "kurwanya puncture". Ninini yamakuru, nibyiza biranga.
Ibaruwa ya gatanu yicyongereza nayo yerekana "gukata gukata", ariko igipimo cyikizamini gitandukanye nicy'imibare ya kabiri, kandi uburyo bwo kwerekana urwego rwo kugabanuka rwaciwe nabwo buratandukanye, bizasobanurwa birambuye nyuma.
Ibaruwa ya gatandatu yicyongereza yerekana "kurwanya ingaruka", nayo igaragazwa ninyuguti zicyongereza. Ariko imibare ya gatandatu izagaragara gusa niba ikizamini cyingaruka cyakozwe, kandi niba kidakozwe, hazajya habaho imibare 5.
Nubwo verisiyo ya en en ya 2016 imaze imyaka irenga ine ikoreshwa, haracyari verisiyo nyinshi za kera za gants ku isoko. Uturindantoki twirinda gukata byemejwe nabakoresha bashya kandi bashaje bose ni uturindantoki twujuje ibyangombwa, ariko birasabwa cyane kugura uturindantoki twirinda gukata dufite imibare 6 n’inyuguti kugira ngo werekane ibiranga uturindantoki.
Hamwe no kuza kwinshi mubikoresho bishya, birakenewe ko ubasha gutondekanya muburyo bworoshye kugirango ugaragaze ko uduce duto duto duto. Muburyo bushya bwo gutondekanya ibyiciro, nta tandukaniro riri hagati ya A1-A3 numwimerere 1-3, ariko A4-A9 ugereranije numwimerere 4-5, naho ibyiciro bibiri byumwimerere bigabanijwemo amanota 6, ashobora gukoreshwa uturindantoki. Gukata birwanya gukora ibisobanuro birambuye kurwego rwo gutondekanya imvugo.
Mubisobanuro bya ANSI, ntabwo imvugo yerekana urwego gusa yazamuwe, ariko kandi nibipimo byikizamini. Mu ntangiriro, ikizamini cyakoresheje ASTM F1790-05 gisanzwe, cyemereraga kwipimisha ku bikoresho bya TDM-100 (igipimo cy’ibizamini cyitwa TDM TEST) cyangwa ibikoresho bya CPPT (igipimo cy’ibizamini cyitwa COUP TEST). Noneho ikoresha ASTM F2992-15 isanzwe, yemerera gusa gukoresha ikizamini cya TDM ikora ikizamini.
✬Ni irihe tandukaniro riri hagati y'Ikizamini cya TDM n'IKIZAMINI CY'IGIKOMBE?
IKIZAMINI CY'IGIKOMBE gikoresha icyuma kizunguruka gifite umuvuduko wa 5 Copernicus kugirango uhindukire kandi ugabanye ibikoresho bya gants, mugihe TDM TEST ikoresha umutwe wicyuma kugirango ikande ku bikoresho bya gants ku muvuduko utandukanye, bisubize ku muvuduko wa 2.5 mm / s gukata lazeri
Nubwo shyashya en 388 risaba ko ibipimo bibiri byikizamini, COUP TEST na TDM TEST, bishobora gukoreshwa, ariko munsi ya COUP TEST, niba ari byiza cyane birwanya anti-laser bikata ibikoresho bibisi, uruziga ruzenguruka rushobora guhinduka. Niba lazeri igabanije Nyuma yincuro 60, irabaze ko umutwe wogukata uba mubi, kandi IKIZAMINI cya TDM ni itegeko.
Twabibutsa ko niba iyi gants yo gukora cyane irwanya laser yo gukata ikizamini cya TDM, noneho "X" irashobora kwandikwa kumibare ya kabiri yuburyo bwo kugenzura. Muri iki gihe, kurwanya kugabanuka kugaragazwa gusa n’inyuguti ya gatanu y'Icyongereza.
Niba atari kubutumwa bwiza bwo kwihanganira gukata, noneho ibikoresho bya gants ntibishobora gutesha umutwe umutemeri wa COUP TEST. Muri iki gihe, IKIZAMINI cya TDM kirashobora gusibwa, kandi imibare ya gatanu yuburyo bwo kugenzura yerekanwa na "X".
Ibikoresho bibisi bya gants zidasanzwe zidasanzwe byapimwe ntabwo byageragejwe kubizamini bya TDM cyangwa birwanya ingaruka. Material Ibikoresho bito bya gants nziza zidashobora kwihanganira, IKIZAMINI cya TDM cyarakozwe, IKIZAMINI CY'IGIKOMBE hamwe n’ikizamini cyo kurwanya ingaruka nticyakozwe.
